AdSigner vs Signally

AdSigner centrally manages employee email signatures and can deploy them across an organization. It supports distinct branded signatures for departments, roles, regions, locations, or company brands. Campaign banners can carry offers, events, content, or company news in employee emails. Analytics tracks signature and campaign views, clicks, and click-through rates, with reports exportable to Excel, CSV, or JSON. Employee directory data can be synced from Microsoft Entra ID or Google Directory, supplied through JSON endpoints or custom API sources, or imported from Excel, CSV, or JSON files. Deployment options include Microsoft 365 and Outlook add-ins, Google Workspace and Gmail add-ons, AdSigner Agent for Outlook or Thunderbird, HTML copy-and-paste, and API-based deployment. AdSigner says it processes directory data and signature configuration to generate signatures without routing or accessing email content. Its security page states that it is GDPR compliant, offers a Data Processing Agreement, and has an SSL certificate. Administrators can enforce disclaimers and restrict compliance settings through role-based permissions. Standard support is included with subscriptions, with email or chat responses within 24 business hours. The platform lists API, extension, web, and Windows.

Signally manages company email signatures and banner campaigns. Its drag-and-drop editor lets users assemble signatures without writing HTML, while fields can be populated from Microsoft Entra ID or Google Directory. Administrators can assign templates by subsidiary, brand, department, country, or group, and lock selected fields. Banner campaigns can be scheduled, targeted by team, and measured with click statistics. Integrations include a Microsoft 365 and Outlook add-in and a Google Workspace and Gmail add-on. The Google add-on can be deployed domain-wide from the admin console, with templates organized by group or organisational unit. Signatures can be previewed for Outlook on Windows and Mac, Outlook Web, Gmail, Apple Mail, iOS, and Android. Signally says it does not read, analyse, or store email content, and messages do not pass through its servers. Its infrastructure is in France, and service data is not transferred outside the EU, according to the maker. The free editor supports manual creation and installation; automatic company-wide deployment and campaigns require a subscription. The paid plan includes all features and lists rates from €1.50 per month for 1–10 users down to €0.50 per month for 500+ users, excluding VAT.
